Refine Botwoon ETank right-side shinecharges

[blkerby]

• The existing strats required 2 runway tiles in order to stutter water shinecharge here. This PR adds 1-tile options, with the canPreciseStutterWaterShineCharge tech. With 1 runway tile, it requires a 1 or 2 frame release of forward, and a last-frame forward repress, which seems ok for Expert.
• Options are added to go back out through the right door with temporary blue or shinecharged. For the "Leave Shinecharged" variants, I just copied the strats from Aqueduct. In theory, the slopes will slow down your horizontal movement while running into the room, making it so you cover relatively more ground while spin jumping back out. So for some of these it should be possible to leave with slightly more frames remaining here compared to Aqueduct, but I don't think it's significant enough to bother changing the strats.
• I added a junction node (7), since like in other rooms, there are several ways to gain the blue speed and also several ways to use it.

There is some inconsistency with 7 being right of the sand while also breaking the speed blocks when you enter the node. It'd be nice if that could be cleared up somehow, like by saying 7 is a longer stretch within the speed blocks. But if not, the obstacles are overall cleared how they are supposed to be.

Ah, right. This got mixed up because I initially defined 7 as being by the left door, then changed it to be right of the sand because it makes more sense for the 7->4 leaveWithTemporaryBlue. I updated it now so that the obstaclesCleared happens in the 7->1 strat instead of in the strats that end at 7.
